đĄđĄLinkMe: A MetaFilter experiment for postsđĄđĄ
Hi, MetaFilter moderator here, posting an experimental thread, based on a recent suggestion by Rhaomi. Here's the idea, paraphrasing:
"Find a neat article, video, blog, etc. but don't feel up to the work of cobbling together an FPP, tags, title, and otherwise putting yourself out there? Just comment "LinkMe:" followed by the link and maybe a one sentence description for context. Everybody has tacit permission to turn your link into an FPP if they'd like, first come first serve, with a nod back to the original LinkFilter comment"
An example of the type of comment to make is inside, but don't feel bound to that exact format! [more inside]

Food experiments from 1994 & 1998
Some gems of the Old Web (note, posts do not link to video):
June 1994: And, if you take a grape, cut it in half but leave the sides attached by a piece of skin, and then microwave it. Sparks!
August 1994: If you leave a pop-tart in a toaster too long, the results are... incendiary.
And from 1998: Marshmallow Peep research [more inside]

Goldfish learned how to drive during about a dozen 30-minute lessons.
In a new experiment, six goldfish learned to drive a tank of water on wheels around a room. This feat of steering suggests that fishesâ navigational abilities hold up even on land. Illustrated by cartoonist JoAnna Wendel as part of the Wild Things series for Science News Explores.
Effect of Humming on Vision
Whatâs cooler than being cool?
Controversy continues over whether hot water freezes faster than cold water, decades after teenage Erasto Mpemba initiated the first systematic, scientific studies. In the effort to confirm or refute the âMpemba effectâ physicists are developing new theories about how substances relax to equilibrium.
Survivor of "Elan School"'s Harrowing Tale
elan.school is a harrowing webcomic now in 61 installments (the latest posted August 27) by a survivor of the "Elan School", a reform school in the woods of Poland Springs, Maine. The school, which operated from 1970 to 2011 when it was shut down, used cult methods, forcing kids to scream insults at each other hours a day, remain expressionless while being insulted, box each other in a ring, and confine others to sit in the corner. Communication with family was closely supervised to keep the abuse hidden. The webcomic may have started in late 2018 to judge from author "Joe Nobody"'s Patreon, but has been garnering attention on Reddit

Long time till spring
A seedbank-testing experiment that started in 1879 has decades to run. It's a simple experiment, but the simple things are hard: neither losing the seeds nor digging them up too early. From the point of view of the *seeds* the simple thing -- don't germinate until you can grow -- is also getting pretty hard. [more inside]

A social experiment without consent, oversight or regulation
A quantum experiment suggests thereâs no such thing as objective reality
Physicists have long suspected that quantum mechanics allows two observers to experience different, conflicting realities. Now theyâve performed the first experiment that proves it. They use these six entangled photons to create two alternate realitiesâone representing Wigner and one representing Wignerâs friend. Wignerâs friend measures the polarization of a photon and stores the result. Wigner then performs an interference measurement to determine if the measurement and the photon are in a superposition.
The experiment produces an unambiguous result. It turns out that both realities can coexist even though they produce irreconcilable outcomes, just as Wigner predicted.
That raises some fascinating questions that are forcing physicists to reconsider the nature of reality.
Finnish Basic Income experiment: positive psychological effects
Finland's two-year experiment with Basic Income have concluded, and the preliminary results are out (Kela.fi x2). The take-aways are generally mixed to pessimistic, many similar to this Fortune article title: Finland's Basic Income Experiment Kind of Works, but Not in Employment Terms. In short, while the âŹ560 (~$630) per person per month, given to 2,000 people, wasn't enough to boost employment, those BI recipients were happier and less stressed, a result that was apparent after only four months (Business Insider). While Finland chose to end the experiment here, as the Government rejects request to expand scheme and plans stricter benefits rules (Guardian), others are trying their own Basic Income experiments (Huffington Post).

People use basic income to improve their quality of life
Universal basic income hasn't made me rich. But my life is more enriching: "The Finnish basic income trial, of which I am part, finishes at the end of the year. Having been interviewed by nearly 70 separate media outlets, from the BBC to Le Figaro, the question I have been asked most often has been: how has the basic income trial changed my life? My answer is simple. In money terms, my life has not changed at all. However, the psychological effects of this human experiment have been transformative. I vastly prefer basic income to a benefits system fraught with complicated forms, mandatory courses and pointless obligations... it gives you security to chase other opportunities. It pushes you to seek fulfilling work â and isn't that what unemployment benefits should do?" [more inside]

Music Alters Mood Alters Visual Perception
Music Alters Visual Perception "As illusory percepts are believed to reflect the content of internal representations that are employed by the brain during top-down processing of visual input, we conclude that top-down modulation of visual processing is not purely predictive in nature: mood, in this case manipulated by music, may also directly alter the way we perceive the world."
Should Leftists Support UBI?
âThe rogueâs gallery of right-wing supporters, from Milton Friedman to Charles Murray, is often unambiguous in its desire to use basic income as a knife to eviscerate the expensive insides of the welfare state. To different degrees, recent support within elite tech-chauvinist circles, from Peter Thiel to Mark Zuckerberg, might be similarly understood. How on earth could Marxists form a political alliance with the boy-king of Silicon Valley? Perhaps some elites see basic income as a pragmatic means to avoid the radicalization of a population that has seen little improvement in living standards in recent years, but others envision a Trojan horse designed to raid the citadels of Social Security, Medicare, and education spending.â Debating Universal Basic Income - David Calnitsky (Catalyst)
CAN YOU TELL IF TWO CHIMPANZEES ARE RELATED BY LOOKING AT THEIR PHOTOS?
Well, can you, punk?
The Great Ape Dictionary needs your help! In our experiment, hosted by Gorilla.sc, you will see a photo of a chimpanzee and four possible matches. Can you tell who is related to who? Mothers, fathers, brothers, sisters â theyâre all there! Humans can recognise biological relatives through facial features; we want to explore how kin-based facial recognition evolved in humans and other primates.

âIf you went in the room when it was switched on, youâd burn directly,â
German scientists are switching on âthe worldâs largest artificial sunâ in the hope that intense light sources can be used to generate climate-friendly fuel. [The Guardian] âThe Synlight experiment in Jülich, about 19 miles west of Cologne, consists 149 souped-up film projector spotlights and produces light about 10,000 times the intensity of natural sunlight on Earth. When all the lamps are swivelled to concentrate light on a single spot, the instrument can generate temperatures of around 3,500C â around two to three times the temperature of a blast furnace.â

Can smiling make you happier? Maybe not. We have no idea. ... The basic finding of Strackâs researchâthat a facial expression can change your feelings even if you donât know that youâre making itâhas now been reproduced, at least conceptually, many, many times. ... In recent years, it has even formed the basis for the treatment of mental illness. An idea that Strack himself had scoffed at in the 1980s now is taken very seriously: Several recent, randomized clinical trials found that injecting patientsâ faces with Botox to make their âfrown linesâ go away also helped them to recover from depression.

Have a Guinness (Latte) when you're tired
Starbucks Is Testing a Drink That Tastes Like Guinness (Without the Alcohol) by Samantha Grossman (@sam_grossman), Time magazine:
The new drink, called the Dark Barrel Latte, is being tested at select locations across Ohio and Florida, Grubstreet reports. It doesn't contain any alcohol, but it supposedly contains the dark, toasty, malty flavors of Guinness. A BuzzFeed writer who got his hands on one in Columbus confirmed that it really does taste like stout. Several customers who've tweeted about the drink agree that it tastes like Guinness — but the jury's still out on whether or not thatâs actually a good thing.[more inside]
When I asked a colleague who was born and raised in Dublin (Guinness's birthplace) how he felt about all this, he responded first with this GIF. Then, as he mulled it over a bit more, he added, "Holy hell. Worst." Then he posed a question: "American Guinness already doesn't taste like Guinness. So what will this taste like?" Then he barfed all over me and my stupid American ignorance.

Male Scent May Compromise Biomedical Research
Jeffrey Mogilâs students suspected there was something fishy going on with their experiments. They were injecting an irritant into the feet of mice to test their pain response, but the rodents didnât seem to feel anything. âWe thought there was something wrong with the injection,â says Mogil, a neuroscientist at McGill University in Montreal, Canada. The real culprit was far more surprising: The mice that didnât feel pain had been handled by male students. Mogilâs group discovered that this gender distinction alone was enough to throw off their whole experimentâand likely influences the work of other researchers as well. [more inside]
